Primary Examiner-James A. Leppink AttorneyBernard Kriegel ABSTRACT: A retrievable packer with a large passage area and control valve connected thereto are run and set in a cased well bore. A plug is set in the valve, after which a tubing is connected to the plug and fluid pressure applied thereto to open the valve so that gas from the well or reservoir can flow through the packer and opened valve into the tubing-casing annulus and into a gas delivery line at the top of the well bore. The valve is tapered to provide a greater annular area between it and the well casing to allow unrestricted flow of gas from the well at a very high rate. In the event of damage to the surface equipment, the well pressure automatically closes the control valve. The valve can be closed whenever desired and the tubing string removed, after which the plug and control valve and packer are removable from the well casing through use of wireline equipment, and without the necessity for killing the well.

DEA/v APPARATUS FOR CONTROLLING FLUID FLOW FROM GAS STORAGE WELLS ANI) RESERVOIRS The present invention relates to well bore apparatus, and more particularly to subsurface apparatus for controlling the flow of fluid between the well bore and reservoir communicating therewith and'the top of the well bore.

Prior devices are known for automatically shutting off fluid flow from a well bore in the event of damage to the surface connections, as, for example, to the wellhead or to a delivery pipe line. If gas is being produced from a gas well or underground gas storage reservoir, disruption of the surface connections will be accompanied by a substantial drop in gas pressure and thereby effect automatic closure of a safety valve disposed in the well bore. In connection with gas storage wells, it is necessary to withdraw gas at a very high rate during peak demand periods. However, prior devices embodying subsurface safety shutoff valves have had insufficient flow area therethrough, and between such devices and the well casing in which they are located, imposing severe restrictions on the rate at which the gas can flow. As an example, in the US Pat. application of Gonzalo Vasquez and John V. Salerni, Ser. No. 752,366, filed Aug. 13, 1968, for Disaster Valve," a sleeve valve is disclosed to which a plug can be latched for the purpose of closing the passage therethrough, such that a predetermined gas pressure differential can shift the sleeve valve longitudinally of an associated valve housing for the purpose of shutting off the valve. However, the valve housing or body is comparatively close to the wall of the surrounding well casing, reducing the annular area through which the gas can flow, such gas proceeding upwardly through a tubing-casing annulus to the delivery line at the top of the well bore.

In prior equipment, such as that exemplified in the aboveidentified patent application, it is desirable to employ a well packer having a maximum flow passage therethrough. However, the advantages of a large flow passage through the packer are nullified to some extent by the restriction that the safety shutoff valve offers to the flow of fluid into the tubingcasing annulus. Moreover, in the prior devices it has not been possible to run the well packer and safety valve in the well casing, or to retrieve such parts from the well casing, without killing" the well; that is, filling the well bore with heavy drilling mud, or the like. The killing of a well is costly, and is associated with the possibility of damage to the well bore and the reservoir.

By virtue of apparatus embodying the present invention, the well packer and safety valve can be both run in and retrieved from the well casing without killing" the well, and under safe conditions. Accordingly, expense and possible damage to the well bore and reservoir are avoided. In addition, the safety valve employed has a large port area through which the gas, or other fluids, can flow, the safety valve being such that the annulus into which the gas flows from the ports has a much greater area than was heretofore possible to provide, thereby permitting the gas to flow through a large diameter packer passage, ports with large areas, and a large tubing-casing annulus to the top of the well bore, and without restrictions. Accordingly, during peak operating periods, gas can be withdrawn from the gas storage well or reservoir at very high rates. In the event of damage or failure to the equipment, the safety valve automatically shuts in the well. Closing of the safety valve is also effected whenever desired from a remote point. More specifically, a predetermined pressure drop in the tubing string connected to the apparatus and extending to the top of the well bore will cause the gas, or other fluid, pressure below the valve to automatically effect its closing.

In connection with running the apparatus into and retrieving it from the well casing, the packer, safety valve, and all accessories can be lowered and removed through use of wire line equipment, such as an electric wire line, piano wire line, or a sand line, such equipment being lowered into the well casing through use of a known type of lubricator, such that the operations can take place under pressure and without the necessity for killing" the well. The well packer employed is capable of being anchored to the casing in packed-off condition against movement in both longitudinal directions and of being released and retrieved at the well casing through use of wire line operated equipment.

This invention possesses many other advantages, and has other purposes which may be made more clearly apparent from a consideration of a form in which it may be embodied. This form is shown in the drawings accompanying and forming part of the present specification.

In FIGS. 1a and 1b, a somewhat diagrammatic illustration of a portion of the apparatus embodying the invention is disclosed, with the parts in position for delivering gas from an underground reservoir (not shown) to a gas delivery line 10. A well bore 11 extends downwardly from the ground surface to the location of the gas reservoir, there being a suitable master valve 12 at the top of a casing 20, the gas delivery line controlled by a valve 13, and a suitable head 14 communicating with a fluid pressure line 15, from which fluid under pressure can pass into a tubing string 16 connected to the head and extending downwardly in the well casing to operative connection with a safety valve 17 secured to a well packer 18 depending therefrom, which is illustrated as having been anchored in packed-off condition in the well casing 20. The gas will flow from the reservoir into the packer l8 and out through ports 21, 22 in the safety valve above the packer into an annulus 23 surrounding the safety valve, flowing upwardly through the tubing-casing annulus 24 to the gas delivery line 10.

The well packer can be lowered in the well casing and anchored therein in packed-off condition against movement in both longitudinal directions. It includes a main or tubular body 25 (FIGS. 9d, 9e, 9]) the lower end of which is threadedly secured to a body latch sleeve 26 having a plurality of depending spyinglike arms 27 terminating in lateral outward directed latch fingers 28 adapted to be disposed under an inwardly directed circumferential shoulder or flange 29 integral with a thrust sleeve 30, the lower end of which is threadedly secured, belowthe latch fingers, to a lower thrust sleeve section 31 (FIG. 9]). A retainer sleeve 32 is disposed within the upper portion of the extension 31, being held initially in a position closely behind the latch fingers 28 be a shear screw 33, in order to retain the latch fingers under the thrust sleeve shoulder 29. The body latch sleeve 26 can only move to a limited distance downwardly along the thrust sleeve by engagement of its latch fingers with the upper end 34 of the thrust sleeve extension 31. Upward force imposed upon the retainer sleeve 32 is transmitted from its lower flange 35 to a downwardly facing shoulder 36 on the extension sleeve 31, with which it is: in engagement when the shear screw 33 is intact. The upper ends of the latch fingers 28 and their companion shoulder 29 are inclined in a downward and outward direction so that an upward pull taken on the body 25 and its latch sleeve 26 will tend to cam the latch fingers 28 laterally inwardly from engagement with the shoulder or flange 29. However, such action cannot occur so long as the retainer sleeve 32 is located behind the latch fingers.

Shearing of the screw 33 by imposing a downward force on the retainer sleeve 32 will enable the latter to shift downwardly to a position below the latch fingers 28, allowing the latter to shift laterally inwardly. The extent of downward movement of the retainer sleeve 32 is limited by its engage ment with a split stop ring 37 confined within an internal groove 38 in the extension member 31. Such downward movement is obtained as a result of engagement of a tool part, described hereinbelow, with an upwardly facing shoulder 39 in the retainer sleeve, the tool being guided into the sleeve by a downwardly tapering upper surface 40 on the retainer sleeve.

The upper end of the thrust sleeve 30 is threadedly secured to a lower abutment ring 41 slidably mounted on the periphery of the body 25 (FIG. 9e). This abutment ring engages the lower end of a packing assembly 42, the upper end of which contacts an upper abutment ring 43 initially secured to the body 25 by a shear screw 44. As specifically illustrated, the packing assembly 42 includes a plurality of elastomer packing elements 45 engaging the upper and lower abutments 43, 41 and separated by metallic spacer sleeves 46. Relative movement of the upper and lower abutments 43, 41 toward each other will compress the packing elements 45 and expand them outwardly into firm sealing engagement with the wall of the well casing 20 and the periphery of the body 25.

The upper abutment 43 is threadedly secured to a lower expander 47 engaging initially retracted lower slips 48 adapted to be expanded outwardly upon relative'downward movement of the lower slips along the lower expander, by virtue of slida ble engagement of the inner downwardly and outwardly inclined inner surfaces 49 on the slips with companion tapered surfaces on the lower expander. Relative separating move ment between the lower slips 48 and lower expander 47 will cause retraction of the lower slips because of opposed side tongues 50 on the lower slips engaging in companion grooves 51 in the lower expander (FIG. 11), the tongues and grooves being inclined in the same direction and to the same extent as the expander surfaces 49. The upper ends of the lower slips 48 are formed as T-shaped heads 52 radially slidable in companion slots 53 in a slip ring 54.

The upper end of the slipring 54 has similar T-shaped slots 55 receiving the lower T-shaped heads 56 of a plurality of circumferentially spaced upper slips 57 engageable with an upper expander 58 initially. secured to the body by a shear screw 59 when the slips 48, 57 and packing assembly 42 are in retracted position (FIG. 9d). The inner surfaces 60 of the slips 57 are inclined in an upward and outward direction, engaging companion surfaces in the upper expander 58, such that relative longitudinal movement toward each other between the upper expander and upper slips will effect radial outward expansion of the upper slips against the well casing 20. Similarly, relative longitudinal separating movement between the upper expander and upper slips will effect retraction of the upper slips toward the packer body 25 because of the inclined side tongues 61 on the upper slips received with companion grooves 62 in the upper expander, the tongues and grooves being inclined to the same extent as the expander surfaces 60 on the upper expander and slips.

The expander 58 has an extension sleeve 63 integral therewith and extending upwardly therefrom, which is slidable along the periphery of the body 25. This extension sleeve is connected to a connector sleeve 64 extending upwardly from the expander 58 and encompassing the extension sleeve, the lower end of the connector sleeve engaging an upwardly facing shoulder 65 on the upper expander. The upper end of the connector sleeve is threadedly secured to a connector sub 66 having an upper left-hand threaded box 67 threadedly secured to a valve body section 68 disposed therewithin. The upper expander 58, although initially engaged by the lower end of the connector sleeve 64, is movable downwardly to a small extent relative to the latter by virtue of a one-way or ratchet interconnection 69 therebetween (FIGS. 9e, 13b). Thus, the expander extension sleeve 63 has a plurality of upwardly facing ratchet teeth 70 on its periphery engaging companion downwardly facing ratchet teeth 71 on a split lockring 72 having external cam teeth 73 thereon engaging companion internal cam teeth 74 in the connector sleeve 64. Thus, the extension sleeve 63 and upper expander 58 can move downwardly
